Simpsons shitposting started in the early 10s when a lot of barely literate favelados bough laptops and started using facebook. They got to MSPainting simpsons characters wearing their favourite futbol clubs
People then discovered there was dozens of Simpsons futbol graffities spread though Buenos Aires favelas and the meme took a life of it's own
/int/'s /lat/ was one of the early adopters. Then came late-stage Taringa. Then facebook Simpsons meme pages started doing it unironically as some of the shittiest relatable comic parodies you can image.
Much later otaku reddit subs adopted it as a way to "subtly" be anti-poor (class divisions in argentina are like race divisions in the USA) and the meme blew up and got super schizo.
This all happened like 10 years before english speakers started doing simpsons edits. Suck my dick gringos we did it first
